Boku wa Natsukashii Piano (僕は懐かしいピアノ, I am a Nostalgic Piano) is AKB0048's 575th major single (577th overall), and is the 17th single of the new era. It also acts as Ikuta Erika the 11th graduation single.

Ever since that day,
I kept my finger on this key
Regardless of the harsh winds,
its seemingly endless sound is calming
"Seemingly"

A sound that could cause ripples on a clear blue lake
A sound that could grant miracles (just believe)
A sound within my heart, a sound that I can make
I gather all of my feelings for a crescendo

All the hardships we've been through, they're gone with the melodic wind
But one day, they'll return
Though, we shouldn't fret (if we close our eyes)
Nostalgia will hit soon
Shall we rejoice, or should we be disheartened by this song?
The decision is yours,
but I recommend that you remember both, the good and bad memories,
and surely one day you'll smile

You'll remember the melody

Ever since that day,
I tried to hold a fermata
but with the cold atmosphere,
I couldn't help myself but shiver
"help myself"

A warm smile that could change a cold heart
A warm smile that could cure beliefs (have faith in you)
A smile that I once forgot, an expression that I can make
I'll give Dolce a try

Nostalgia hits once again while you play the piano,
but don't worry about me, I'm fine
as long as you don't cry (then I don't want to open my eyes)
But that's expected
Shall we continue to worry about what happens next?
In my opinion, let's focus on our goodbye notes
Jumping up the octave won't be easy,
but smile and do your best

Nostalgia's on your side

Thinking about moving on, it doesn't seem so hard,
but once you get onto the stage, seeing the ones who love you,
it truly hurts
As a new path becomes visual, like when we met,
I'll give this a try with determination

All the hardships we've been through, they're gone with the melodic wind
But one day, they'll return
It's okay to remember (it's okay to close your eyes)
Let your feelings out once more
I will be no more than a nostalgic piano,
something that could be claimed (although my heart belongs to you)
Maybe one day, I'll stand on my own
Then again, I'm looking forward to meeting you again
